The problem

You know what you're talking about. Publishing it every week is the hard part.

Every issue starts with a blank page and a long day of writing, and when you try AI, it doesn't sound like you. So you skip a week, then another. When an issue does go out, hardly anyone sees it, and the audience you could've built never finds you.

How it works

From idea to audience in three steps

1

Teach it your brand

Share three writing samples and connect your website. Flyletter learns your voice and your brand, and keeps learning every time you publish.

2

Pick a topic and go

Bring an idea or choose one of Flyletter's topic suggestions. It outlines, drafts and polishes the issue in your voice, ready for your final edits.

3

Promote it

Flyletter writes social posts you can publish in a click and optimizes every issue for Google and AI search, so new readers keep finding you.

Your voice

A brand profile that sounds like you

Connect your website, newsletter, or share a few writing samples, and Flyletter builds a brand profile with complete context on your voice, audience and positioning. Your profile updates every time you publish.

Publish ready drafts, on your schedule

Choose a topic. Flyletter outlines and drafts the issue in your voice, then edits out anything that reads like AI. Review the outline first, or set a schedule and wake up to finished drafts. Export issues to Beehiiv or Kit.

What our users say
“Flyletter writes the issue and the social posts in the time I used to spend on one channel alone.”
Andrew Lane
Andrew LaneFounder, Design Hacker

“I tried writing newsletters in ChatGPT for months. Every issue meant a multi-prompt sequence and hoping the output didn't drift. Flyletter has the content team built in.”

Tyler Barr
Tyler BarrFounder, Punch Financial

“Fashion content has its own language, and most AI tools produce generic style content. Flyletter captured my voice. The way I phrase things, the references I use, the words my audience knows me for.”

From the founder
Evan Tarver, Founder of Flyletter
“I've been writing for years. Built and sold a content business, ran growth at a startup, self-published books for fun. But I couldn't keep a consistent newsletter. I spent months prompting ChatGPT and Claude. It took longer than just writing it myself. So I built Flyletter. Now my newsletter goes out every week, generates organic subscribers, and brings me sales calls I never went looking for. I built it for me, and now for you.”

Questions

Frequently asked questions

Keep them. On Pro, Flyletter works inside Claude and ChatGPT. It adds the system around the writing: a brand profile built from your website, newsletter or writing samples, topic suggestions from your own content, issues drafted in your voice, social posts that promote each one, and search optimization for every issue you publish.
That depends on the quality of what you connect: your website, newsletter or a few writing samples. The brand profile captures voice mix, tone, sentence rhythm, vocabulary, structural patterns, and the words you'd never use. The first newsletter you generate is the proof. Read it and decide.
No. Flyletter writes social posts that promote every issue and optimizes each one for search, so each issue can reach people who aren't subscribed yet.
Flyletter compiles what is measurably true about how you write into a structured brand profile, and every agent reads it before it writes. The profile updates every time you publish, and your edits surface voice insights you can accept.
On Pro, Flyletter sends newsletter drafts to Beehiiv or Kit. Kit connects with an API key, and one click puts the draft in your Kit account. Beehiiv drafts go through Claude and Beehiiv's own connector, so the draft is built in your usual template. Two connectors need a paid Claude plan, since Claude's Free plan allows one. For Substack, Ghost and other platforms, you copy the text into your editor. On Pro, social posts publish to LinkedIn, X and Threads.
Yes, with Flyletter's connector, on Pro. It runs the whole workflow from a chat: outline and write your newsletter, plan, write and publish your social posts, write emails and pages in your voice, and update your brand profile as you go. Newsletters and posts you write in Claude or ChatGPT run on your own Claude or ChatGPT account, so they never count toward your plan. The connector works on every Claude and ChatGPT plan, Free included.
You do. Your writing samples, your brand profile, and every generated draft belong to you. Your profile is not used to train shared models or accessible to other accounts. If you cancel, you can export everything before you go.
Yes. Every account starts with a free 14-day trial of Pro, with no credit card. During the trial you have everything in Pro: the Claude and ChatGPT connector, social posting, sending drafts to Beehiiv or Kit, 20 newsletters in the app and 3 brand profiles. When it ends you choose Creator or Pro, or your account pauses with your work saved.
Write as many as you like in Claude or ChatGPT on Pro. In the app, extra newsletters past your plan's monthly count are $5 each on Creator and $4 on Pro.
Yes. Cancel from your account dashboard. No phone calls, no retention friction, no surprise charges.
